BOOT-TREEING MACHINE.

SPECIFICATION forming part of Letters Patent No. 324,982, dated August 25, 1885.

Application led October 9, 1884.

T0 all whom it may concern.'

Beit known that I, JAMEs GALL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Boot-Treeing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Fignre l is a perspective view of my im- Fig. 2 is a vertical section of the mechanism for holding and locking the boot-tree to the screw-shaft. Fig. 3 is a transverse section through the screw-shaft and feed mechanism. Fig. 4 is a longitudinal section through the driving mechanism.

This invention has for its object to produce a simple and effective machine for treeing boots, and it consists in certain details of construction and combinations of parts, as will be hereinafter more particularly set forth and specifically claimed.

In the drawings, A represents the frame of the machine, upon which is supported in snitable standards, b c, a long shaft, B, having a screw-thread cut thereon for a considerable portion of its length, for a purpose presently to be explained.

C is a bevel-gear which is splined upon the shaft B and rotates the saine, the bevel-gear receiving its motion from another bevel-gear, d, mounted upon a shaft, a, which has its bearings in astandard, c, as seen in Fig. 4.

Near the bevel gear d, 'and on the same shaft, is a large gear, f, which meshes with a smaller gear, g, upon a shaft, h, supported in the standards e, and upon the opposite end of this shaft li is another large gear, z', which meshes with a smaller gear, It, upon a shaft, Z, the inner end of this shaft being turned down and fitting within a recess formed in the end of the shaft c,- and between the standards c is a clutch-pulley, m,wliich revolves loosely upon the shafts a Z. Upon either side of this pulley is a pin or projection, which is brought into contact with similar projections upon the shafts a Z, according as the clutch-pulley is moved to one side or the other for the purpose of rotating the same.

When the pulley is moved by the shipperlever a toward the bevel-gear, the shaft a is rotated thereby, and when moved in the oppo- (No model.)

site direction the shaft Z is rotated, and through the gears 7a t' g f the shaft a is rotated, an increased or decreased rate of speed of the shaft c being thus produced,according as the pulley engages with the projections on one or the other of the shafts a l.

p is a sliding clamp to hold the pulley m in a central position, so as not to engage with the projections upon the shafts a Z.

Secured to the outer end of the screw-shaft by means of a bolt is an ordinary expanding boot-tree, over which the boot to b e treed is placed, the central rod, q, of which is attached to a block, r, which projects outside the shaft B through a slot, s. To the upper end of this block r is secured a short rod, t, which eX- tends up outside the shaft B through a slot, u, and has pivoted at its upper end a spring arm or lever, t, the inner end of which bears upon a short lever, w, having a projection, fr, which engages in the teeth a on the shaft B.

D is a foot-treadle pivoted to the frame A, and is held in position by means of a spring. b is a short connecting-rod pivoted to the treadle, and at its upper end to another connecting-rod, c', to which is pivoted the lower end of a rod, d', which proj ects' u p through a slot in the frame, to which it is pivoted, its upper end being brought into contact with the block 1' by depressing the treadle D, for the purpose of moving forward the said block, when the short lever w will catch into aiiotcli and hold the boot in place, as desired, when stretched.

E is a long lever pivoted in the standard c, the end of this lever being secured to a strap, c', the ends of which are attached to a block, f', having a screw-tliread cut on its under side, which engages with the screw-thread on the shaft B, for the purpose of feeding forward the saine when brought in contact therewith by 'means of the lever E, the block f being kept in contact with the screw-shaft by means of aspring, as seen in Fig. 3.

G is a long lever pivoted by means of screwrods g to abifurcated standard, H, rising from the frame A, this lever being adjusted longitudinally by means of the nuts h', for the purpose of lengthening or shortening the length of the lever, according as a longer or shorter boot-tree is upon the shaft B. This lever G is provided with an arm or offset, I, to the IOO outer end of which is pivoted abent arm or lever, J, which has pivoted to its lower end a rubber or burnisher, 7c', which, as the boottree is revolved and fed forward by the screwshaft B, passes over every portion of the boot placed upon the tree and smooths out the wrinkles and properly trees the boot in an expeditious manner.

L is an arm provided with acurved outer end, and adapted,when swung down,to smooth the wrinkles between the sole and upper, and after it has done this is swung up out of the way on its pivot Z', so as to allow the burnisher to finish the work. The burnishcr is kept downto its Work by means of one or more spiral springs, m, attached to the lever J, the opposite ends of the springs being provided w1th iings, which slip over the arm a of a slotted guide secured to the arm l. I

Vhen the machine is in operation, the lever G rests upon a bar secured to a bifurcated standard, M, rising from the front of the frame, and this lever is assisted in heilig raised by means of a weight, p', attached to the end of a cord, q', said cord passing over suitable pulleys to the lever G, to which it is attached, and thence passes over another pulley to a pin projecting from the standard M, over which it is caught.

What I claim is as follows:

l. In a machine for treeing boots, the combination, with a pivoted rubber, of a boot tree mounted upon the end of a revolving screw-shaft, and means, substantially as described, for feeding forward the said shaft, as herein set forth.

2. In a machine for treeing boots, the conibination, with a pivoted rubber, of a boottree mounted upon the end of a screw-shaft, mechanism connected therewith for rotating the same, and means, substantially as described, for feeding forward the said shaft, all constructed to operate as described.

3. In a machine for treeing boots, the rubber 7c', pivoted to the lever J, in combination with the arm or lever G, made adjustable l0ngitudinally, substantially as and for the purpose described.

4. The combination, with the rotating shaft B, )rovided with ratchet notches or teeth and having secured to its outer end aboottree, of the ratchet-lever w, secured to the end of a block, 1, upon the central rod, q, of the boottree, and mechanism, substantially as described, for actuating the said lever, all constructed and arranged to operate substantially as set forth.
